p5-getopt-long 2.37_0 cannot be staged into destroot

[stephan@…]

During an install of gnucash on an intel iMac using OS X 10.5.2 I ran into a problem staging p5-getopt-long into destroot. I checked before and this port was not installed before, so it appears the perl58 port already brings its own version of getopt-long. However, this behavior is rather irritating, especially since there is getopt-long inside the base port for perl plus an additional port with a potentially newer version.

Known issue. You'll notice that it says right in the output you pasted, "You must install or activate this package with '-f' (force) as it needs to overwrite files installed by the perl5.8 port."
